The quantification of organochlorine pesticide (OCP) residues continues to be an important area in residue chemistry. Continual improvements in sample extraction and analysis provide more sensitive and robust methods for the determination of OCP residues in many matrices. Among the more challenging matrices are liver and eggs. With their high lipid content, clean-up of sample extracts from these matrices presents a unique challenge. Through the use of a combined-phase solid phase extraction cartridge, the extraction of OCP residues in these biological matrices has been greatly improved. Combining this improved extraction with a dual column ECD analysis has permitted the quantitation of twenty OCPs in these challenging matrices.
